I guess while there were some restrictions in my kids library. I just didn't rely on the school library being their man source of books, most of my kids read books that I'd bought either through Scholastic book club or the excellent local children's book shop nearby. In school they were allowed to take out a book in their AR level for K-3rd and one free choice. Honestly my son was mostly taking out non-fiction books in K-2nd grade. One of the ways that I managed to make sure he could check out appropriate books was I volunteered to help at library time and got to know the librarians and the library that way.
